Is set. In addition, level 1 (1 [MB / sec] or more and less than 10 [MB / sec]) usable information allows chat (O), IP phone is unstable (△), and video conference is not possible (×). Is set. In addition, level 2 (10 [MB / sec] or more and less than 100 [MB / sec]) available information allows chat (◯), IP phone (◯), and unstable video conference (△). Is set. In addition, level 3 (100 [MB / sec] or more) usable information is set to allow chatting (O), IP telephone (O), and video conference (O).

  Note that the available information stored in the available information storage unit 66 may differ for each model or for each installed program.
